PROCESS FOR THE MANUFACTURE OF METAL FORKS AND SPOONS.

Specification of Letters Patent.

Application filed. January 3, 1910.

Patented May 14:, 1912.

Serial No. 536,088.

To all whom it may concern:

Be it known that I, ARTHUR \VILZIN, of 100 Boulevard Victor Hugo, St. Ouen, Seine, Republic of France, engineer, have invented Processes for the Manufacture of Metal Forks and Spoons, of which the following is a full, clear, and exact description.

The invention relates to a method for producing with a minimum of skill and operations, spoon and fork blanks practically without any scrap. This method is based on the use of a profiled piece, substantially flat in shape, and of about the same thickness throughout its length, having substantially the same weight and nearly the same length as the finished graded blank, but narrower in surface, said profiled piece presenting at different points of its length cross-sections essentially equal in surface to the cross-sections of the blanks as required for the final design stamping. I obtain such profiled pieces by submitting to anyshaping method which does not involve loss of stock (such as hammering, compressing, squeezing, upsetting, drawing-out, rolling, edge-pressing, etc.) rods, bars, strips or blanks of such shape as may be cut from the raw material without or with little scrap. The profile pieces thus obtained are then thinned or crushed out sidewise between grading dies or rolls, thereby imparting to them the outlines and differences in thickness required for the final design stamping.

The process is herein exemplified with reference to the manufacture of a spoon blank.

In the accompanying drawings Figure 1 shows a round rod a substantially of the same weight as the spoon blank and of a diameter corresponding substantially to the mass of metal required in its shank. This rod is transformed by means of one of the well-known upsetting machines into a profiled piece a Fig. 2, of which Figs. 3 to 10 are cross sections made respectively on lines F-F; GG; H--I-I, II, JJ, KK, L- L, and M-M. This profiled piece is shaped to substantially the length of the final blank desired. Fig. 11 shows, in front view, the finished spoon blank developed.

Fig. 12 is an edge view of the same, showing the graded thicknesses. Figs. 13, 14, 15. and 16 show cross sections made respectively according to lines N-N, O-O, P-P, QQ of Fig. 11; these section lines are made at the points corresponding to the section lines G-G, I-II-I, JJ and LL of the profiled piece illustrated in Fig. 2. The cross sections represented by Figs. 6 and 7 correspond in area to that in Fig. 15, the cross section in Fig. 4 corresponds to the area of cross section in Fig. 13; Fig. 5 to Fig. 14:; Fig. 9 to Fig. 16.

Instead of a round rod a one of square, oblong or oval section may of course be used, in which case the sections shown in Figs. 6 and 7 would of course be correspondingly shaped instead of being round.

The profiled piece a may be obtained by any other means involving no loss of stock. In some cases it may be advantageous to form a plurality of such profiled pieces a on one bar and separate them ultimately. Each profiled piece a is then submitted to a simple flattening action, preferably by dies so as to widen and grade it into a blank a (Figs. 11--16) presenting the contour and thicknesses as required for the final shaping or design stamping.

For the manufacture of forks I proceed in a similar way in order to obtain the blanks required for the final stamping.

It is to be understood that the present process may be applied to the manufacture of forks and spoons or flatware handles of any shape or size.

Evidently the profiled piece may have an oval or oblong cross sectlon instead of being rectangular.

What I claim is:

A process for the manufacture of blanks for forks, spoons and the like, which consists in submitting to a thinning and grading action a profiled piece of practically the same thickness throughout its length and of the same weight and nearly of the same length as the finished graded blank, and so shaped as to present at the various points of its length, different cross-sections, essentially equal to the cross-sections at corresponding points of the finished fork or spoon blank, said thinning action widening spoons, signed by me this seventeenth day out and grading the blank into a blank of of December, 1909.

' the contour and thicknesses required for the final design shaping and stamping of a ARTHUR WILZIN' spoon or fork. Witnesses:

The foregoing specification of my process DEAN B. MASON, for the manufacture of metal forks and R. EHIRIOT.
